The first file has a white balance issue. It is slightly blue. The blue is more obvious in the shadows.
I believe the depth of field of the first file is shallow. While removing texts from the objects is not a quality issue, it is another reason for refusal if the submission is for commercial licensing and the texts poses an IP problem in which case you need to remove them.
The second file is also slightly blue. It would have been better if you had caught all the carriage without the leg in the forefront and a wider crop at the handle.
The third file is underexposed. It has a focus issue which is visible when zoom in at 100%. Also, I cannot identify a subject in this picture, thus a composition issue.
The fourth too has a white balance issue. It is slightly blue and the depth of field is too shallow.
AGP_9661.jpg - not good composition, not sharp on the edges AGP_9661.jpg - not sharp, no Commercial value AGP_9640.jpg - not sharp, no Commercial value AGP_9706.jpg - not sharp on the edges, no Commercial value
AGP_9640.jpg - composition is also a problem here. No object is completely in the frame. These appear to be cellphone snapshots taken at a rummage sale. I question whether there is any commercial appeal to such images.
